Bad diet causes cognitive decline: Fact or myth?
Published : Dec 16, 2022 16:42 IST More than 400-500 calories per day of ultra-processed foods such as burgers, chips and packaged cookies is enough to increase the risk of cognitive decline, a new study suggests. The study, involving 10,775 men and women in Brazil, found people who ate more ultra-processed foods had a 28 per cent faster rate of global cognitive decline compared to people who ate the least amount of ultra-processed foods over an eight-year period. With people in countries like the US and the UK getting over 50 per cent of their dietary intake from ultra-processed foods, the study, published in JAMA Neurology, indicates concerning health consequences. “This study only provides an association between intake of ultra-processed foods and cognitive decline,” said Duane Mellor, a dietitian at Aston University in the UK not involved in the study. Unhealthy foods are causing major global health problems Quibbles about individual studies aside, medical and nutrition experts like Mellor agree that diet and nutrition are two of the biggest risk factors for people’s health across the globe today.
